Answer Engine Optimization treats every surface — featured snippets, AI Overviews, ChatGPT, Perplexity, voice assistants — as different renderings of the same underlying job: deliver the answer. AEO unifies them under a single playbook.

The AEO framework

  1. Pick the question.
  2. Write the canonical answer in 40–80 words.
  3. Surround it with disambiguating context.
  4. Reinforce with schema and internal links.
  5. Measure presence in every answer surface.

Signals AEO depends on

  • Question-shaped headings with stable anchors.
  • Self-contained answer paragraphs (no anaphora).
  • FAQPage, HowTo and QAPage schema.
  • Entity consistency across the web.
  • Topical authority of the host.

Content patterns

AEO favors definition-first posts, comparison tables and step-based how-to guides. Narrative essays underperform because they bury the answer.

Metrics

  • Answer share: % of priority questions where you own at least one answer surface.
  • Surface coverage: across SERP features, AI Overviews, ChatGPT, Perplexity.
  • Sentiment: how the model describes you when it answers.

Common pitfalls

  • Optimizing for clicks rather than answers — you lose the slot.
  • Skipping schema — you lose eligibility.
  • Ignoring branded queries — you lose the easiest wins.

Frequently asked questions

Is AEO different from GEO?
AEO is a superset that covers all answer surfaces. GEO is the LLM-specific subset.
Do featured snippets still matter?
Yes. They are the SERP analog of an LLM citation — and they correlate with AI Overviews eligibility.
How many questions should I target?
Start with 25 priority questions. Expand to 100 once you own at least 60% of them.
